Default String Utils to search all words in filenames

Is there a String Utility out there I could use to search a string with 2 or more words against filenames?

For example, I have this string, "Black Cat", and I have the following filenames:
    "Black_Cat.jpg"
    "Black Cat.jpg"
    "Cat.jpg"
    "Cat Is Black.jpg"
    "Cat is black.jpg"
    "Color - black.jpg"
    "Black Catcher.jpg"
    "Black cat22.jpg"
    "Black Cat_22.jpg"

I like to the String Utility to return me True for the 1st, 2nd, 4th, 5th, and 9th filenames.

Please help

Save the following little ruby script and execute it if you wish.

Code:
----- BEGIN SCRIPT -----
#!/usr/bin/ruby -w
#
# Following solution can be run from the command line, e.g.:
#
#    $ ./this_program.rb "Black Cat"
#

def all_words_in_filename?(terms, filename)

  result = false

  # Each matching term cannot be followed by an
  # alphanumeric value in the filename.
  terms.each do |term|
    if filename =~ /#{term}(?![a-z0-9])/i
      result = true
    else
      result = false
      break
    end
  end

  return result
end

# Presumably, the following hard-coded array would be dynamically
# populated from reading a directory from disc.
file_list = [
             'Black_Cat.jpg',
             'Black Cat.jpg',
             'Cat.jpg',
             'Cat Is Black.jpg',
             'Cat is black.jpg',
             'Color - black.jpg',
             'Black Catcher.jpg',
             'Black cat22.jpg',
             'Black Cat_22.jpg',
            ]

search_words = ARGV[0].to_s
if search_words.empty?
  puts 'missing multi-word argument'
  exit
end

terms = search_words.split(/\s+/)

i = 1
print "\nSearch Terms: #{terms.join(', ')}\n\n"
file_list.each do |file|
  result = all_words_in_filename?(terms, file)
  a = result ? '*' : ''
  number = (a + i.to_s).rjust(2)
  puts "   #{number}. #{result.to_s.ljust(5)} #{file}"
  i += 1
end
----- END SCRIPT -----
